[Bitrise co-founder here] We have a fastlane integration step ;) That said imagemagick & ghostscript are not pre-installed, but you can install both with a simple script step. All of the integrations (https://www.bitrise.io/integrations) are open source and you can add your own with a Pull Request to our Step Library anytime. You can check out what's preinstalled on our VMs here: http://devcenter.bitrise.io/docs/virtual-machines-updates
